    Center is (7,-3) and radius is 8

    Step-by-step explanation:

    Equation of circle with (h, k) as center and radius r is given by,

    (x-h) ² + (y-k) ² = r²

    Here we need to find the radius and center of the circle given by the equation (x-7) ² + (y+3) ²=64

    Changing equation to (x-h) ² + (y-k) ² = r² form

    (x-7) ² + (y+3) ²=64

    (x-7) ² + (y - (-3)) ² = 8²

    So, h = 7, k = - 3 and r = 8

    Center is (7,-3) and radius is 8
